Our research objective is to perform theoretical analytical studies on the effects of an attractive electron-electron interaction on electron transport through a quantum dot. To this end, we want to study a minimal model that features all necessary characteristics but still allows for maximal control over these characteristics, namely a quantum dot on a mechanical nanoresonator. Our prospective findings could indicate analogies to the pairing mechanism of cooper pairs in superconductors or contribute to applications in the field of nanoelectromechanical systems. Beyond the fundamental insights into single electron transport, our results could thus also be relevant to foreseeable technology applications: e.g., to single-electron-transistors (computers) or to nanoelectromechanical sensors (smartphones).
